Cardiac Perfusion Imaging using a Combination of CAIPIRINHA & Compressed Sensing

Daniel Stb¹, Tobias Wech¹, Christian Oliver Ritter¹, Dietbert Hahn¹, Herbert Kstler¹

A combination of CAIPIRINHA simultaneous multi-slice imaging with Compressed Sensing is presented. A technique is generated, accelerating the imaging procedure in slice and phase encoding direction. In the reconstruction process, Compressed Sensing is used to eliminate incoherent artifacts, while a parallel imaging reconstruction separates the simultaneously excited slices. The technique was applied for high resolution myocardial perfusion imaging with extended anatomic coverage. Different sparsifying transforms for the Compressed Sensing reconstruction were examined in terms of systematic and statistical errors.
